Struct std::net::Ipv4Addr1.0.0 [] [src]

pub struct Ipv4Addr { /* fields omitted */ }

Representation of an IPv4 address.

Methods

impl Ipv4Addr
[src]

Creates a new IPv4 address from four eight-bit octets.

The result will represent the IP address a.b.c.d.

Examples

use std::net::Ipv4Addr;

let addr = Ipv4Addr::new(127, 0, 0, 1);Run

Returns the four eight-bit integers that make up this address.

Examples

use std::net::Ipv4Addr;

let addr = Ipv4Addr::new(127, 0, 0, 1);
assert_eq!(addr.octets(), [127, 0, 0, 1]);Run

Returns true for the special 'unspecified' address (0.0.0.0).

This property is defined in UNIX Network Programming, Second Edition, W. Richard Stevens, p. 891; see also ip7.

Examples

use std::net::Ipv4Addr;

assert_eq!(Ipv4Addr::new(0, 0, 0, 0).is_unspecified(), true);
assert_eq!(Ipv4Addr::new(45, 22, 13, 197).is_unspecified(), false);Run

Returns true if this is a loopback address (127.0.0.0/8).

This property is defined by RFC 1122.

Examples

use std::net::Ipv4Addr;

assert_eq!(Ipv4Addr::new(127, 0, 0, 1).is_loopback(), true);
assert_eq!(Ipv4Addr::new(45, 22, 13, 197).is_loopback(), false);Run

Returns true if this is a private address.

The private address ranges are defined in RFC 1918 and include:

  • 10.0.0.0/8
  • 172.16.0.0/12
  • 192.168.0.0/16

Examples

use std::net::Ipv4Addr;

assert_eq!(Ipv4Addr::new(10, 0, 0, 1).is_private(), true);
assert_eq!(Ipv4Addr::new(10, 10, 10, 10).is_private(), true);
assert_eq!(Ipv4Addr::new(172, 16, 10, 10).is_private(), true);
assert_eq!(Ipv4Addr::new(172, 29, 45, 14).is_private(), true);
assert_eq!(Ipv4Addr::new(172, 32, 0, 2).is_private(), false);
assert_eq!(Ipv4Addr::new(192, 168, 0, 2).is_private(), true);
assert_eq!(Ipv4Addr::new(192, 169, 0, 2).is_private(), false);Run

Returns true if the address is link-local (169.254.0.0/16).

This property is defined by RFC 3927.

Examples

use std::net::Ipv4Addr;

assert_eq!(Ipv4Addr::new(169, 254, 0, 0).is_link_local(), true);
assert_eq!(Ipv4Addr::new(169, 254, 10, 65).is_link_local(), true);
assert_eq!(Ipv4Addr::new(16, 89, 10, 65).is_link_local(), false);Run

Unstable (ip #27709)

: extra functionality has not been scrutinized to the level that it should be stable

Returns true if the address appears to be globally routable. See iana-ipv4-special-registry.

The following return false:

  • private address (10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16)
  • the loopback address (127.0.0.0/8)
  • the link-local address (169.254.0.0/16)
  • the broadcast address (255.255.255.255/32)
  • test addresses used for documentation (192.0.2.0/24, 198.51.100.0/24 and 203.0.113.0/24)
  • the unspecified address (0.0.0.0)

Examples

#![feature(ip)]

use std::net::Ipv4Addr;

fn main() {
    assert_eq!(Ipv4Addr::new(10, 254, 0, 0).is_global(), false);
    assert_eq!(Ipv4Addr::new(192, 168, 10, 65).is_global(), false);
    assert_eq!(Ipv4Addr::new(172, 16, 10, 65).is_global(), false);
    assert_eq!(Ipv4Addr::new(0, 0, 0, 0).is_global(), false);
    assert_eq!(Ipv4Addr::new(80, 9, 12, 3).is_global(), true);
}Run

Returns true if this is a multicast address (224.0.0.0/4).

Multicast addresses have a most significant octet between 224 and 239, and is defined by RFC 5771.

Examples

use std::net::Ipv4Addr;

assert_eq!(Ipv4Addr::new(224, 254, 0, 0).is_multicast(), true);
assert_eq!(Ipv4Addr::new(236, 168, 10, 65).is_multicast(), true);
assert_eq!(Ipv4Addr::new(172, 16, 10, 65).is_multicast(), false);Run

Returns true if this is a broadcast address (255.255.255.255).

A broadcast address has all octets set to 255 as defined in RFC 919.

Examples

use std::net::Ipv4Addr;

assert_eq!(Ipv4Addr::new(255, 255, 255, 255).is_broadcast(), true);
assert_eq!(Ipv4Addr::new(236, 168, 10, 65).is_broadcast(), false);Run

Returns true if this address is in a range designated for documentation.

This is defined in RFC 5737:

  • 192.0.2.0/24 (TEST-NET-1)
  • 198.51.100.0/24 (TEST-NET-2)
  • 203.0.113.0/24 (TEST-NET-3)

Examples

use std::net::Ipv4Addr;

assert_eq!(Ipv4Addr::new(192, 0, 2, 255).is_documentation(), true);
assert_eq!(Ipv4Addr::new(198, 51, 100, 65).is_documentation(), true);
assert_eq!(Ipv4Addr::new(203, 0, 113, 6).is_documentation(), true);
assert_eq!(Ipv4Addr::new(193, 34, 17, 19).is_documentation(), false);Run

Converts this address to an IPv4-compatible IPv6 address.

a.b.c.d becomes ::a.b.c.d

Examples

use std::net::{Ipv4Addr, Ipv6Addr};

assert_eq!(Ipv4Addr::new(192, 0, 2, 255).to_ipv6_compatible(),
           Ipv6Addr::new(0, 0, 0, 0, 0, 0, 49152, 767));Run

Converts this address to an IPv4-mapped IPv6 address.

a.b.c.d becomes ::ffff:a.b.c.d

Examples

use std::net::{Ipv4Addr, Ipv6Addr};

assert_eq!(Ipv4Addr::new(192, 0, 2, 255).to_ipv6_mapped(),
           Ipv6Addr::new(0, 0, 0, 0, 0, 65535, 49152, 767));Run
